Anthurium plant named &#39;ANTHESBOL&#39;

ABSTRACT

A new and distinct variety of  Anthurium  plant named ‘ANTHESBOL’ particularly distinguished by having very bright pink, heart-shaped, strongly blistered and very durable spathes, green elliptical cordate and glossy leaves, average shoot formation, rich flowering continuously throughout the year, a more stretched and open plant habit and a plant height of 28 cm to 32 cm, is disclosed.

Genus and species: Anthurium andreanum L.

Variety denomination: ‘ANTHESBOL’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium,botanically known as Anthurium andreanum L., and hereinafter referred toby the variety name ‘ANTHESBOL’. The new variety originated from ahybridization made in May 2008 in Bleiswijk, The Netherlands. The femaleparent was a red Anthurium pot plant designated ‘8477-05’ (unpatented),and the male parent was a pink Anthurium plant designated ‘9012-02’(unpatented).

A single plant was selected in June 2010 and has been asexuallyreproduced repeatedly by tissue culture in Bleiswijk, The Netherlandsover a five-year period. The present invention has been found to retainits distinctive characteristics through successive asexual propagations.

Plant Breeder's Rights for this variety have been applied for in theEuropean Union on Nov. 6, 2014. ‘ANTHESBOL’ has not been made publiclyavailable or sold anywhere in the world more than one year prior to thefiling of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishingcharacteristics of this new variety when grown under normalhorticultural practices in Bleiswijk, The Netherlands:

1) Bright, shiny, cordate pink spathe;

2) White spadix with yellow tip;

3) Elliptical cordate dark green leaves.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctivecharacteristics of ‘ANTHESBOL’. The data which define thesecharacteristics were collected from asexual reproductions carried out inBleiswijk, The Netherlands. The plant history was taken on 35-week oldplants which were planted from tissue culture in 14-centimeter pots andgrown in a glass greenhouse between 19° C. and 24° C. Observations weremade in September 2015. Color readings were taken under 5000 lux naturallight in the greenhouse. Color references are primarily to The R.H.S.Colour Chart of The Royal Horticultural Society of London (R.H.S.)(2015).

‘ANTHESBOL’ differs from the female parent plant ‘8477-05’ (unpatented)in that ‘ANTHESBOL’ has pink spathes, whereas ‘8477-05’ has bright redspathes.

‘ANTHESBOL’ differs from male parent plant ‘9012-02’ (unpatented) inthat ‘ANTHESBOL’ has a white spadix with a yellow tip, whereas ‘9012-02’has a pink spadix with an orange tip.

‘ANTHESBOL’ differs from commercial variety ‘PINK CHAMPION’ (U.S. PlantPat. No. 12,115) in that ‘ANTHESBOL’ has a white spadix with a yellowtip, whereas ‘PINK CHAMPION’ has a pink spadix with an orange tipAdditionally, ‘ANTHESBOL’ has a larger spadix length, a larger spathewidth and more strongly blistered spathes than ‘PINK CHAMPION’.

‘ANTHESBOL’ differs from commercial variety ‘ANTHCOPYLI’ (unpatented) inthat ‘ANTHESBOL’ has a white spadix with a yellow tip, whereas‘ANTHOPYLI’ has a pink spadix with an orange tip. Additionally,‘ANTHESBOL’ has a smaller spadix length, a smaller spathe width and morestrongly blistered spathes than ‘ANTHCOPYLI’.

I claim:
 1. A new and distinct variety of Anthurium plant named‘ANTHESBOL’, substantially as illustrated and described herein.
